[SR-Users] How to drop 200 OK in onreply_route ?

[Daniel-Constantin Mierla]

Hello,

if the 200ok is consumed by tm, it will destroy the transaction very
soon. I am not sure this is a good path to go.

If you need to stop the retransmission, a 100 trying should be sent
instead of 200ok. Can you reconfigure the next hop to do that? Or is it
out of your control?

Cheers,
Daniel
